How to Measure

Let us help you find the perfect fit! Remember to measure more than one finger as they will vary in size, measure when your hands are warm, cold weather can shrink your finger and to ensure that you will be able to fit the ring over your knuckle.

Option 1 - Measure An Existing Ring

Find your favourite ring.
Take a ruler or measuring tape and measure the inner width of the ring.
Take a note of the millimetres, not centimetres.
Use our size chart above to find your perfect size.

Option 2 - Measure Your Finger

Cut a string that is about 10cm long.
Fold the string around your finger, below the knuckle (where you would like your ring to sit).
Mark the piece of string where the two ends meet.
Use a ruler or measuring tape to measure the length in millimetres.

Option 3 - Use our ring sizer

Simply push the end through the buckle to form a ring shape.
Adjust the width around your finger until you are comfortable and confident that it won't slip off.
Take a note of which number the arrow is pointing to (in our example, it would be 9).
Use our size chart above to find your perfect ring size.
